ROC curve of the level of A LVEF, B NT pro BNP, C FBS, D LCR in predicting the occurrence of CI-AKI after primary PCI. LVEF, left ventricular ejection fraction; NT-proBNP, N-terminal pro-B-type natriuretic peptide; FBG, fasting blood glucose; LCR, lymphocyte to C-reactive protein ratio; CI-AKI, contrast-induced acute kidney injury
